"While my husband is still in the hospital recovering from his multiple surgeries, we are living every parent's worst nightmare," Judge Esther Salas said. "Making preparations to bury, bury our only child, Daniel."
She and her son Daniel were cleaning up after celebrating his 20th birthday when the shooter arrived at their home in North Brunswick.
"We were chatting, as we always do," the judge said. "And Daniel said, 'Mom, let's keep talking. I love talking to you, Mom.' And it was at that exact moment that the doorbell rang. And Daniel looked at me and said, 'Who is that?' And before I could say a word, he sprinted upstairs. Within seconds, I heard the sound of bullets and someone scream no. '"
"Daniel, being Daniel, protected his father," she continued. "And he took the shooter's first bullet directly to the chest. The monster then turns his attention to my husband. And began to shoot at my husband."

He was later found dead by suicide.
Judge Salas is calling for action to address the lack of privacy afforded to federal judges.
"I am begging those who are in power to do something," she said. "For my family, the threat was real and the free flow of information from the Internet allowed this sick and depraved human being to find all our personal information and target us."
